' Application filed nine 14,

To all whom it may] concern Be it known that I, Tn'onon NADoLNY, citi zen of Republic of Poland, residing at'Elizabeth, in the county of Union and State of New Jersey have invented new and useful Improvements in Look lowing is'a specification.

This invention relates to a; lock of the'type wherein-a number of movable elements must be arranged in a certain relationto permit the shackle to be withdrawn to unlocking position, the general objectiofthe invention being to provide a pluralityof reversible ring members each having two sets of indication marks thereon so that new combinations'can be provided by reversing the ring. and by'interchanging them? Another objectof the invention is to pro-; vide a slidable member for looking the other limb of the shackle A-still further object of the invention'is to providemeansifor holding the rings in place with springs-pressed locking means for such means which are heldin locked posi; tion by the shackle when the'same is in closed This invention also consists in certain other features of construction and in. the combination-and arrangementof the several parts, to be hereinafter fully described, illustrated in the'accompanying drawings and specifically pointed out in the appendedclaims. h

In describing my invention indetail, reference will be had to the accompanying I drawings wherein like characters ,denotelike or corresponding part's throughoutthe sev-'% eral views, andinwhich:1 f

2 where it takes the form of groove 4. "One limb vided with an extension 5 for engaging this groove and this extension is provided The four ring members 6 fit over the extension and are held in place I v the stem 8 of which passes 9.'1n the extension with the by the member through a hole head 10 engaging the end of the extension. This head is of practically the'same diameter as the rings and :carries a pair of pins 11 which engage holes-12 pins act to properly ber on the extension; with a central collar in the stem; These position the mem- 13 which is knurled so that the ring can be easily rotated by the "thumb and finger and a set of indication marks and numerals11' are placed 011 the ring at each side of the collar. Only one by reversmg one or more rings or rearranging the rings new combinations can be secured, Each ring is also provided with an interior flange 1 5 for engaging the notches 5 in'the shackle and each flange is interrupted, as

at 16, for disengaging'the shackle from the r l a semi-circular, 0ft theshackle 1s pro- Each ring is formed flange. It will be understood that when all i the rlngs are arranged with the spaces 16 reglstering with each "other'and with the notched part of the shackle, said shackle can be withdrawn without interference upon (the part of the rings. 7 p r The member 7 is held'in position by means of a pin 17 engagin notch 18 in the inner end of the stem 8 o said member, this pin a 3 being slidably mounted in a transverse hole "A spring QO'tends to force the pin out of the notch but said pin is'held in engagement with the notch by the beveled end 21 19 in the lock case.

and the short limb of the shackle engagingthe head of the pin when the shackle v is in closed position When the shackleis. in open position the spring will force the pin out of the notch sothat the member 7 can'be withdrawn. Said member "7 'must be forcibly withdrawn from the device as it is frictionally'held therein when the pin is inoperaive position. The short limbof the shackle is provided with anotchi22which is ar-' ranged adjacent the beveled end 21 and a laterally sliding bolt 23 has a part held in i engagement with said notch 22 by the spring plunger 24. located in a transverse opening 9'3 in the lock case. 'Thisbolt 23'passes through alaterally arranged slot 26 inthe through the sides of the casing with the ends of the bolt projecting from the casing Where they'receive the knurled heads 27." The plunger 24 has its head engaging the long limb ot the shackle and when the shackle is Withdrawn from the lock case to case which is arranged at right angles to the opening 25 and this slot 26 passes aicertain extent this head willenter an annular groove 28 immediately above the notch part of theshackletoprevent further Withd'raw'al of the shackle. However, in this position the short end of the shackle will clear the top of the case sothat the shackle can be turned topermit itcto engage oi be dis- 1 engaged from the part to be locked. An

arroiv'29 is placed at-thelower part of the lock casing" for indicating the settlng points of the two upper rings and a similar arrow is placed on the headlO of member 7 to indicate the setting points of the lower rings. To unlock the device the rings are; turned to bring the proper combination marks opp'osite the arrows 29 and30 so as-to place j [notch 3 0 the'sp'aces l6 ofthe rings over the notched part of the shackle. Bolt 23 is then moved inwardly by pressing upon the heads 27 so as to move said boltout ofengagenient with The shackle willthen be'iree to move outwardly but when groove 28 comes opposite the plunger 24 the spring of said plunger will force the head thereof into said groove andthus-prevent further Withposition;

draw'al ofthe shackle. The shackle is then turned to free it from or engage it with the part'to be locked; 'When the shackle is I in unlockedwposition the member 7 can be Withdrawn to change the combination by reversing or interchanging the rings on the extension 2. hen the shackle is pushed in the bolt 23" will be forced into the notch 22 by the spring plunger so, as to hold the shackle in closed position and then if it is desired to prevent an unauthorized person from openingthe lock it is simply necessary to rotate the rings'to placethe flanges into engagement with the'notches 5-. VVh'en the shackle ispushed in, its beveled end engaging pin 17 will force the end of said pin into engagement with the notchlS of the memher 7 to lock said member and the rings in One side of the shackle adjacent the groove 28 is beveled, as at 28, to permit the spring plunger to move out of the groove when the shackle is pushed inwardlv- I It is thoughtfrom the foregoing descrip tion that the advantagesand novel features of my invention will be readily apparent.

I desire it to be" understood that I may make changes in the construction and in the 3 combination and arrangement of the several 1 parts, provided that such changes fall w thin the scope of the appended claims.
